This essay explores and assesses the connection between accountability and the quality of democracy in modern Greece along three key dimensions: vertical, horizontal, and social. Vertical involves elected officials and the three branches of government; horizontal deals with the nonelected arms of government and bureaucratic agencies; and social addresses civil society, the mass media, and nongovernmental organizations. Examination and analysis of the relevant data indicate that the state of accountability in Greece is weak in all three dimensions, and a host of structural, social, and attitudinal factors contributes to this weakness. Accountability problems undermine the quality of democracy. The essay expresses hope that reforms initiated under pressure from the European Union eventually would strengthen accountability and Greece’s quality of democracy.
